So a few weeks ago I was having issues with one camera not connecting and live view would not work. Read all the forums and others have had this issue too it seems. Well, I figured mine out. I had just put brand new batteries in all the cameras. Apparently sometimes you’ll get a bad battery and it’ll csusr the camera to malfunction. I tested this theory by thanking the batteries from the non working camera and switching them with the batteries from another. Every camera I put the batteries from the nonworking camera in failed to connect. So I put two different new ones in and it works like a dream. This may already have been figured out but if not, maybe it’ll help someone who’s getting frustrated!
